mountaintop.

On either hand towered mighty peaks thousands of feet higher than the pass through which they were entering the forbidden valley. Behind him stretched the wooded valley across which they had marched for many days, and at the opposite side the low range which marked the boundary of their own country.

But before him was the view that centered his attention. Here lay a desolate valley--a shallow, narrow valley dotted with stunted trees and covered with many great bowlders. And on the far side of the valley lay what appeared to be a mighty city, its great walls, its lofty spires, its turrets, minarets, and domes showing red and yellow in the sunlight. Tarzan was yet too far away to note the marks of ruin--to him it appeared a wonderful city of magnificent beauty, and in imagination he peopled its broad avenues and its huge temples with a throng of happy, active people.

For an hour the little expedition rested upon the mountain- top, and then Tarzan led them down into the valley below. There was no trail, but the way was less arduous than the ascent of the opposite face of the mountain had been. Once in the valley their progress was rapid, so that it was still light when they halted before the towering walls of the ancient city.

The outer wall was fifty feet in height where it had not fallen into ruin, but nowhere as far as they could see had more than ten or twenty feet of the upper courses fallen away. It was still a formidable defense. On several occasions Tarzan had thought that he discerned things moving behind the ruined portions of the wall near to them, as though creatures were watching them from behind the bulwarks of the ancient pile. And often he felt the sensation of unseen eyes upon him, but not once could he be sure that it was more than imagination.

That night they camped outside the city. Once, at midnight, they were awakened by a shrill scream from beyond the great wall. It was very high at first, descending gradually until it ended in a series of dismal moans. It had a strange effect upon the blacks, almost paralyzing them with terror while it lasted, and it was an hour before the camp settled down to sleep once more. In the morning the effects of it were still visible in the fearful, sidelong glances that the Waziri continually cast at the massive and forbidding structure which loomed above them.

It required considerable encouragement and urging on Tarzan's part to prevent the blacks from abandoning the venture on the spot and hastening back across the valley toward the cliffs they had scaled the day before. But at length, by dint of commands, and threats that he would enter the city alone, they agreed to accompany him.

For fifteen minutes they marched along the face of the wall before they discovered a means of ingress. Then they came to a narrow cleft about twenty inches wide. Within, a flight of concrete steps, worn hollow by centuries of use, rose
